Extra considerations for drivers of LCVs

Truck operators must undergo extensive training to receive a commercial driver’s license and be cleared to begin hauling heavy loads across Texas. According to Trucking Truth, when a truck pulls more than one trailer at a time, the operator of this longer combination vehicle must undergo extra training to learn to compensate for the challenges that are unique to these configurations.

The training for an endorsement to pull two trailers does not include a driving test on the Texas roadways, but a written test must be passed. Truckers must answer questions that demonstrate they know how to handle LCVs and understand the procedures for dealing with sway, rollover and twisting potential in steady turns, off-tracking of the rear wheels, and steering and sensory responses.

The Texas Commercial Driver’s License Manual explains that the responsibilities of operators pulling two or even three trailers go beyond the driving knowledge and skills required. For example, the normal walk-around inspection that every driver must do is more complex because of the extra features present on LCVs, such as the increased number of axles, connections and lines, tires and air brakes.

Coupling and uncoupling of two and three LCV trailers is another area where the procedures are different from those involving a single trailer. They must be attached in order of weight, with the heaviest first and the lightest last. Although there are some standard rules about how to connect the dollies to the trailers, variations on these may also apply based on manufacturer specifications, and truckers should take the time to learn the procedures of every LCV they drive.
